Genes affected

TCEAL5 (HGNC:22282): (transcription elongation factor A like 5) This gene, which is located on the X chromosome, encodes a protein which contains a BEX (brain expressed X-liked like family) domain. This domain is found in proteins encoded by the TCEAL elongation factor (transcription elongation factor A (SII)-like) gene family also located on the X chromosome. The coding region for this gene is located entirely in the terminal exon. [provided by RefSeq, Sep 2011]
